* Promise vs Observable
  * Promise
    * Single async event that can either complete or fail once.
    * Can be used with async/await keywords.
  * Observable
    * Can emit multiple events async. 
    * Offers a bit more control over the async task, for example cancelling. 
    * Cannot be used with async/await keywords.
  * Think of Observables as a stream of data instead of an async task.
  * Observable is the default used in Angular, but promises are still fine to use.

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>
